I know people who make yurts - Mongol tents - the neat thing about these are that the exterior walls are hinged latticework, and the roof is put together something like an offcenter wheel - there is a wooden ring, into which poles are inserted at an angle,which then rest on the latticed wall frames. The modern version of the yurt has UV stabilized vinyl exterior and bubble foil insulation behind it.
So, I says to myself, self I says - wouldn't they be able to make a lattice about 3 feet high that you could hang the wall fabric on and just surround the whole trailer with? of course you'd want to make sure the height was below the furnace, water heater and fridge vents.
Just a thought.
Yesterday is history,
Tomorrow is a mystery,
Today is a gift,
that's why they call it the present.
